Vinteo Server Licensing

Licensing principles

Vinteo licensing the number of simultaneous connections of participants to conferences and the availability of functionality. There are two licensing methods: licensing by ports (1 port = 1 connection) and intelligent (dynamic) licensing. Dynamic type of licensing - the use of fold-out licenses with the ability to flexibly maneuver between the video resolution in the conference and the number of participants.

The following table shows the types of licensing, their description and periodization of action.

Licensing types

Licensing types	Description	Possible duration of licenses
Dynamic licensing	Fold-out HD video licenses that provide connectivity according to the formula 1*HD=2*SD=0,4*FHD=0,1*UHD The number of licenses for different resolutions is distributed automatically.	Indefinite
Static licensing	Licensing by ports with a fixed number of ports of different resolutions and all available licensing options.	Indefinite
Legacy (legacy static licensing for closed distribution)	Licensing by ports with a fixed number of ports of different resolutions and a limitation on the number of licensing options (does not support current licensing options).	Indefinite/terminable
NLS (Network Licencing Server)	Network licensing server that provides work with Dynamic and Static license pools.	Indefinite/terminable

Server edition licenses

The server edition type according to the licensing type is shown in the table below.

		Possible licensing type
	Maximum number of simultaneous calls
Edition type	Static licensing	Dynamic licensing	Legacy (legacy static licensing for closed distribution)	NLS
Base	20 HD	40 SD	20 HD	20 HD
Standard	100 FHD	125 HD	100 FHD	According to the selected licensing type
Enterprise	No limits	No limits	No limits	No limits

Licensing the number of simultaneous connections of participants to conferences

Licensing the number of simultaneous connections can be implemented in two ways: licensing by port; using dynamic (fold-out) licenses.

Licensing by ports

Depending on the availability of video transmission and image resolution 4 types of connections are defined:

• Audio - connection without video; only sound;
• VGA corresponds to a resolution of 640x480 pixels;
• HD - 1280x720;
• FullHD - 1920x1080.

If a client connects to the server with a resolution that does not match one of the basic ones, then the server determines the type of such connection using the following algorithm:

• a base resolution is selected with a minimum value of the product of the vertical and horizontal components of the image resolution (the number of pixels in the one frame); it is no less than the value of the product of the vertical and horizontal components of the image resolution in the connection for which the type is being determined. The type corresponding to the selected base resolution is taken as the connection type.

For example, for a resolution of 1024x768 the HD type will be selected since the product of the resolution components of such a connection is 786432. The minimum base resolution for which the product of the components is greater than or equal to the found value is 1280x720 (921600). When licensing by port the maximum number of each type of connection is set separately, for example:

• Аудио - 20 pcs;
• VGA - 50 pcs;
• HD - 20 pcs;
• FullHD - 5 pcs.

When a client connects to the server (at the time the connection is established) the server checks whether there are free licenses for the connection of the type that the client is requesting.

• If there is a free license of the required type it will be used and the connection will be established.
• If there is no free license of the required type then the server checks for the availability of a free license with a higher resolution than the one requested by the account. If there is one then it will be used. The connection is established with the requested resolution.
• If licenses with a higher resolution are not found then the server checks for the presence of a license with a lower resolution down to the Audio type. If such a free license is found, then it will be occupied and the server establishes a connection with a quality corresponding to this license.
• If there are no free licenses the server will not allow you to establish a connection.

Recording and broadcasting of the conference requires licenses. Connecting a video or rtsp stream to a conference takes one HD license; if one is not available on the server then any free video license will be used. When making a point-to-point call two server licenses are required corresponding to each of the call arms.
